Hex socket bit 5.0 mm across flats, 7 mm socket dia., 4 mm HR shank, 44 mm - Delvo DLB2425

At a cycled assembly station what counts is that the socket sits on the first try and the cycle does not wait for a hand wrench to finish the joint. This bit takes hex heads of 5.0 mm across flats and brings them to final value with the torque set on the screwdriver.

Benefits

• The 4 mm half-round shank runs straight in the H4 holder of the Delvo screwdrivers, so no intermediate piece and none of its play.
• An overall length of 44 mm makes for a stiff bit that wobbles little on approach and does not scuff the flats.
• 5.0 mm across flats at a socket diameter of 7 mm, which keeps access open even between closely spaced heads.
• Hardness grade F, the grade Nitto Kohki intends for bolts and nuts, able to take the shut-off peak of the clutch.
• Special alloy that the manufacturer prepares for screwdriver bits only, with controlled heat treatment and close hardness testing.

Applications

Control cabinet building and machine panelling, mounting of sensor brackets and sheet metal angles, test and rework benches. The bit belongs wherever hex screws and nuts of 5.0 mm across flats are brought to a torque value repeatably.

Matching accessories

The ESD electric screwdrivers DLV-7410-BME6, DLV-7420A BME6 and DLV-7331-BME6 take the bit. Where only a screwdriver with a 1/4 inch holder is at hand, the ADA-HR4-D63 adapter makes the connection. For heads driven overhead, the ring magnets MAG-RING-4,7 and MAG-RING-6,0 hold the screw in place. The NK4DB series also lists 4.0 mm (DLB 2423), 4.5 mm (DLB 2424) and 5.5 mm (DLB 2426).
